[jira] [Commented] (SPARK-6740) SQL operator and condition
precedence is not honoured
[ https://issues.apache.org/jira/browse/SPARK-6740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14731959#comment-14731959 ]

> -----------------------------------------------------
>
> Key: SPARK-6740
> URL: https://issues.apache.org/jira/browse/SPARK-6740
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.3.0
> Reporter: Santiago M. Mola
> Assignee: Santiago M. Mola
>
> The following query from the SQL Logic Test suite fails to parse:
> SELECT DISTINCT * FROM t1 AS cor0 WHERE NOT ( - _2 + - 39 ) IS NULL
> while the following (equivalent) does parse correctly:
> SELECT DISTINCT * FROM t1 AS cor0 WHERE NOT (( - _2 + - 39 ) IS NULL)
> SQLite, MySQL and Oracle (and probably most SQL implementations) define IS with higher precedence than NOT, so the first query is valid and well-defined.
